* Function \ForceUTF8\Encoding::toUTF8

* This function leaves UTF8 characters alone, while converting almost all non-UTF8 to UTF8.

* It assumes that the encoding of the original string is either Windows-1252 or ISO 8859-1.
|

*
|

* It may fail to convert characters to UTF-8 if they fall into one of these scenarios:
|
||||
*
|
||||
* 1) when any of these characters: ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß
|
||||
* are followed by any of these: ("group B")
|
||||
* ¡¢£¤¥¦§¨©ª«¬®¯°±²³´µ¶•¸¹º»¼½¾¿
|
||||
* For example: %ABREPRESENT%C9%BB. «REPRESENTÉ»
|
||||
* The "«" (%AB) character will be converted, but the "É" followed by "»" (%C9%BB)
|
||||
* is also a valid unicode character, and will be left unchanged.
|
||||
*
|
||||
* 2) when any of these: àáâãäåæçèéêëìíîï are followed by TWO chars from group B,
|
||||
* 3) when any of these: ðñòó are followed by THREE chars from group B.
